Question

यदि 56 – 45 + √x = 17, तो x = ?

  1. A. 36 (Correct answer)
  2. B. 25
  3. C. 16
  4. D. 9

Correct Answer

Option A — 36

Detailed Solution & Explanation

The correct answer is 36.

Key Points

  • 56 − 45 = 11, so 11 + √x = 17 → √x = 6 → x = 36.

Exam Tip

  • The radical is faint in most reprints of this paper; without it the equation would give x = 6, which is not among the options — the presence of perfect squares (36, 25, 16, 9) confirms a square root is intended.
